This invention pertains to improvements in presses, and more particularly to that type in U. S. Letters Patent to Anderson, Nos. 731,734; 731,735; and 731,737, dated June 23, 1903, wherein there is shown a shell with a series of separated screws mounted, therein, which screws feed the material throughout the shell, compress the same, and

force the liquid contents, such as oil or the like, therefrom. Working in conjunction with the outlet of the press, as shown in the patents above referred to, means is provided or retarding the outflow and causing the material to be held in the press or shell for the requisite period of time.

The present invention relates more particularly to the means for re ulating the discharge from the press, and takes the place of the cone construction shown in Patent N 0. 731,734, or the head, shell or casing G of Patent No. 7 31,7 35. I Under the present invention, the choke as it may be termed, at the discharge end of thepress is stationary in so far as any rotary movement is concerned, though it is adjustable to vary its eifectivemess with relation to the discharge of the i material, and such adjustment maybe effectis a desirable feature.

'ed while the machine is in operation, whereas under the. old construction where the cone was employed, it was necessary to stop the machine when adjustment was to be brought with the stationary choke of the present case, less friction obtains between the choke and the pressed cake being discharged from the expeller, with the result that the cake'is lighter in color, which Under the old construction where the cone revolves and the cake is forced thereover, the cake becomes hot on account of the friction produced by revolving the cone under the extreme pressure which obtains in presses of this type. Fur-- thermore, by the present construction the press is easier to repair, inasmuch as new parts can be installed without dismantling 1925. Serial No. 33,461.

tion to the constructional advantages above set forth, it has been found that better extraction is effected and a gain as high as 2% obtains over the older forms.

The invention is illustrated in the an-' nexed drawings, wherein,

The expressing means employed may be of any approved type, but I prefer that shown in the patents abovereferred to, and for the purpose of illustration there is shown in Fig. 1 so much of a barrel of the press, together with the screws, as is necessary to a clear understanding of the invention.

Referring to said figure, 1 denotes the shell oi-the press composed of a series of bars held a cylindrical barrel. These bars are backs up y suitable ribs, as 2, which prevent burst- 25 ing of the shell under the high pressure to which it is subjected; The material'to be treated is led in, as through a hopper 3, and comes into working r'elationwith the feeding. screw 4, and is thereafter subjected to the compressive action or the screws or worms 5(i ing suitably braced by ribs to withstand the all of which are carried upon and rotate with a shaft fidriven by any suitable'means .(not shown). I I The shaft atits outer end is supported in a suitable thrust bearing, designated generally by 7, which bearing in turn is secured upon the "frame-work 8 of the machine. Said frame-work, as will be seen upon reference to.

Figs. 1 and 2, is made uite substantial, be-

' strain. It has a semi-circular portion 9', the

walls of which extend downwardly as at 10,

forming a chamber into which the cake is discharged. The lower portion of the walls 8 and 10 bear upon the upper edge of a base 11 into which t e cake'is discharged, 21 iv oted gate 12 being mounted therein to de ect 55 in Fig. 6. It is p Secured to the the caketo one or another conveyor or 're-' cepitacle (not shown) as desired.

Said member is secured to the'outer. face of the housing 15 and the inner ends of the member 21 are bolted to thrust plates 24 and 25 which are housed within the wallof the frame-work 8 of the .machine,.as will be'best seen upon reference to Figs. 1 and 4. Located within the housing 15 is a worm rin or gear 26 (see more paring flange 2 which flange at its 'inner edge is th'ckened and provided with a series ofcam faces 28 corresponding in outline to cum faces 29 formed upon the inner face of the body of the gear. These cam aces28 and 29 are employed 'to actuate the radially disposed members of the choke and serve to move said members inwardl and outwardly towardv or from the shaft and more specifically, toward or from th sleeve 30 WhlOh surrounds the same adj acent the point of discharge of the cake from the shell of the press.

In the form illustrated there are s1x of the radially disposed and adjustable chokeor outwardly under ad ustment. These choke v blocks and their co-operating members which serve to move them inwardly and outwardly are best shown in Figs. 8 to 12 inclusive.

Referrin first-to igs. 8 and 9, the choke block is designated by31, and as will be seen a is formed with an arcuate inner end or face 32 which, in addition to being curved orarcuate in outline stands at an an le with reference to the axle of the machine see Fig.

4). The block is provided in its outer face with a cross slot 33, and outwardly from said a534, so as to provide clearance io'rthe material' after it has-passed. the high end of the arcuate face 32.; The actuator for this blockis shown in Fig.9, is designated generally by 35,; and is provided atits inner end with a curved face 36 which, when the parts are assembled, 'alines with curved face t4, and is likewise provided upon its side with ,,slot, the block is cut awayupon. a curve as two transversely extending lugs or ribs 37 4 nd 38.

channel 33, while the-lug 38 extends across the outer end of the block 31 and backs the same up against Outward thrust during the -slightlyfcurvedflattened face of which,.when

the parts are assembled, bears directly and fully against its corresponding cam 29, while the round member 39 takes against the rel.-

atively narrower cam 28.- Inasmuch as the member'39and the-cam 28 are merely em-' ployed to retract the actuator 35 and its,

choke block, the small cam bearing is all sufficient. The wider cam face 29. however, 'the thrust and is therefore made quite su stantial. 'The actuat'or member 35 passes through the-oppositely disposed chantakes u nel or guide 22- formed inthe hub section heretofore referredto.

The other form of actuator and choke block are shown in Figs..'10 and 11. The choke I block in this instance is, as compared to the block heretofore described, relatively thin or flat. (See also Fig. 4.) The block is designated by 41 and is provided with a turved and beveled or-inclined face 32 cor responding to the face 32 of the other-block, and likewise has formed in'its side face a transverse groove or channel 33. The actuator is designated by 35 and is provided with a transverse rib 37 and a shoulder 38, these parts corresponding in function to the parts 37 and 38. The inner end is curved and beveled or inclined as at 36 to provide clearance for the discharged cake. The same hearing elements 39 and 40 are presentas in the other form of actuator and co-operate with the inner and outer cams 28 and 29 respecgear 26 .in one or another direction will cause tively. When the parts are assembled, the rib 37 finds its seat within the groove 33 and the shoulder 38 takes against the outer end of the choke block 41 and backs the same up against outward thrust.

As will be readily appreciated upon an inspection of Figs. 3 and 4, rotation of the worm an inward or outward movement of the actuators 35 and 35 and the respective choke blocks which are attached thereto. By oflt The outer end of the actuator member 35 is slightly enlarged and is provided with a, transverse opening inworm meshingwith the worm gear 26. Mo-

tion may be imparted to this worm 42 through any suitable mechanism, and in the instant case, such motion is shown as being imparted through a second worm wheel 44 (Figs. 2 and 3) secured'to the'shaft of the worth 42, and motion is imparted to the worm wheel 44 through a worm 45. To the shaft of. this worm is secured .a hub 46carrying aseries of hand arms or levers 47 through which mo- .tion may be applied to'the gear train.

In order to break up the cake as it is discharged from the press, or after it leaves the choke formed of the various choke blocks as above described, there is provided a stud 48 (Fig. 1) which is secured in a sleeve 42 mounted outwardly of the sleeve 30 and the chokeyand rotatable with the shaft 6. Said stud, by reason of its rotation with the shaft and-sleeve, projects into the extruding cake as it passes outwardly from the choke and breaks it up. When located in the position shown in Fig. 1, the cake is broken up into relatively small pieces. By locating the stud outwardly from the choke to a greater extent I than that shown, the cake will not be so finely broken up or divided b thestud.

IVith the construction as, aove described, adjustment of the choke may be had while the machine is in operation, and the various choke blocks moved-inwardly and outwardly simultaneously and to the same extent or degree. I Thusthe discharge of-the cake ma .be easily regulated, a point of manifest a vantage and one which is necessary when treating different classes of material.

Furthermore, the blocks may be readily re-- placed without dismantling the press and removing the outer thrust bearing 7 as is necessary where a .cone choke is employed, as in the -patented.structures above men. tioned.

In so far as the underlying or generic invention is concerned, it is conceivable that the choke blocks, may be independently adjusted toward and from the discharge opening of the press, such construction being shown, however, in my co-pending application, Serial No. 101,507, filed on or about April 26,1926.
